Here's a great idea: Buying unregulated alcoholic drinks on social media. I'm kidding. It's a terrible idea and the trend has health officials in New York City on high alert.

Phrosties are essentially a series of booze-filled slushies available for $10, delivered right to your door, 24/7. Yes, drinks called Tsunami Sunrise, Irish Bomb and Volcanic Paradise can be purchased via Instagram. All you need to do is be accepted as a Phrosties follower and send a simple text to a number posted on the Instagram page.

New York magazine food critic, Adam Platt, tried one and wrote this about it : “After the first sip, you’re loving the sugar. After the third sip, you’re thinking how pretty the colors look and why can’t you feel your lips? After chugging the whole thing, who cares? You’re lying blotto on the sidewalk and all is bliss.

That raises some pretty major concerns, especially from New New York Senator Chuck Schumer. He's worried about children getting a hold of the drinks.

“They seem to be sold online without limitations for age. A 12-year-old could probably buy one and get it and enjoy it because it’s filled with fruit punch and fruit juice,” Schumer said.

Even more troubling is that nobody really knows what's in the drinks.

According to New York’s State Liquor Authority the drink is “unregulated,” and the agency has launched an investigation.

“The SLA is looking into the illegal sale of this unregistered and potentially dangerous alcoholic drink‎ by an unlicensed business,” Bill Crowley, the authority’s director of public affairs, told The Post.
